The COR Vision sliding door from Cortizo is a super slender aluminium system offering outstanding versatility and creating a high-end sliding door solution for any property. The glass is structurally bonded to the sash, allowing for minimal sightlines. The frames can also be embedded into the surrounding walls, maximising the amount of glass on display. This is our personal favourite with the fastest lead times, best value, and the thinnest sightlines in the UK, just 20mm!
